I think the vast majority of metaphors are pointless and end up in most of the discussion being about how the metaphor doesn't make sense or how the magnitude doesn't make sense. They are very frequently used on topics which are quite simple to understand and need no metaphor at all.
The place where I find they make most sense is explaining certain incentive structures. Take for example the Prisoner's Dilemma, you could use this as a metaphor to explain a multitude of situations where people or companies are acting in a way that seems illogical from your perspective but when you simplify it down you can see how each actor has particular incentives.
